I brought a custom laptop from PC Specialist for my daughter who is at uni, as her laptop was begin to show signs of failing. The order number is 2304780 and the total order price is £2,655.00. After receiving notification that the laptop was completed ahead of schedule, I asked if I could pay the extra for weekend delivery and have it shipped straight away. This was the first time I had phone PC Specialist customer support, and the impression I got was very bad. I was told that customer service department had no access to the delivery department and could not even send an email to that department to ask if my request was possible. I waited the extra 4 days for the laptop to arrive. When it did I arrive, I was shocked to hear from my daughter that PC Specialist had installed windows 11 professional. I had specifically stated that I wanted windows 10. I am an IT professional, and I know that the early versions of Microsoft operating systems are for Beta test dummies. I had advised my own company not to install. I phoned customer support, who were initially very accommodating, and told me that they would send a USB to my daughter with a boot-able installation of windows 10, and they would confirm their actions with an email later that day. I did not receive an email, and my daughter did not receive the usb drive. When I phone to find out what had happened, I was simply told that customer service had asked the company, and no USB could be sent. I explained my position on the operating systems, that it was their mistake not mine to install windows 11, and that I had spent £2,655.00 with their company. I explained the distance selling laws which provide the customer with a no quibble right to return any goods within 14 days and told them that If this was not resolved, that I would use this option. I asked to speak to a manager, or a supervisor and I was told that this was not possible, with the only option being that I would receive a callback form a manager within 24 hours. I asked for the customer service representatives name and or staff number. He told me it was "Thomas Dick". I tried to call customer support a number of times. The first time I was on hold, the automated system kept telling me that my call was important and that I had 4 minutes left to wait for over 20 minutes and I eventually gave up. The second time I waited over 30 minutes and finally got through to gentlemen named Stephen. After providing him with my order number he told me that there were no notes on the file, but that he would speak to the person who last spoke to me. I asked for details of this person and was told it was Fran lazzarno who was a supervisor at the company. This is the person who identified himself as "Thomas Dick". After 10 miutes of being put on hold Stephen came back and told me that the issue would not be resolved and there was nothing else he could do. I asked for the name of the manager that was working at the time. I was told it was Mustaffa. I asked to speak to him, and Stephen put me on hold again for 10 minutes. When he came back he told me that he could not find the manager. I asked how many people were working with him that evening and he said 5. I explained that it is very hard to believe that you could lose someone in a team of 5. Stephen said he would try to look for him again and he put me on hold. After 10 minutes the call was surreptitiously dropped. I tried to call back and was left in a holding loop for over 20 minutes. I have emailed the company many times to complain. They have yet to respond to a single mail. I spent £2,655.00, thankfully due to distance selling laws, I can claim my money back now that I have returned their goods. I would never do business with this company, and would urge everyone to think twice before using them.
