WORST COMPANY EVER Applied to transfer to Tonik; after telling me I was now their customer I found out they had bungled transfer from previous energy company and it was delayed for two months. So I was still paying higher charges I had switched to avoid. That was sorted after a lot of hassle; Tonik provide an e-mail contact address abut never answer, just automated reply. Phone waiting times are 30mins plus and sometimes they just cut you off if they're finding your problem is too complex (as also noted by customers in other reviews). At end of a year they wanted to make a big increase in payments with no justification as I wasn't in debt and usage hadn't increased. So I changed supplier. New supplier advised not to close Tonik diect debit yet so they could take last payment/finalise my account. Then I found that Tonik continued to take several regular payments from my account EVEN AFTER I WAS NO LONGER THEIR CUSTOMER. After more long waits on phone got through to an OK advisor who promised to finally settle my account, close it down and repay the payments wrongly taken. This was done and that seemed to be the end of my hassles with these sharks. But no... Now, months later, last week I find a new direct debit set up by Tonik and another payment taken from me. I wait 40mins to speak to Tonik, explain the problem and am then, Tonik admin annoyed at complexity of my problem, I'm cut off. And again Tonik ignore all e-mails. My bank tells me they are "a 3rd party" in this so can't prevent it; the only way I can stop Tonik from repeatedly setting up direct debits is to switch to a new account (with all the accompanying hassle) that they wont have the details of. I had already begun a formal complaint with Tonik but, again, they completely ignore it. next stop - energy Ombudsman. Tonik are the worst company ever and have STOLEN MONEY FROM MY ACCOUNTt: yet they refuse to discuss this with me. And my bank says they can't stop them doing this again unless I close my account! Avoid Tonik like the plague.
