I switched from Tonik to a new provuder, and contacted Tonik numerous times in order to get my final bill produced and my credit balance back. Tonik maintained that they had not had the closing reading from my new supplier but on contacting my new supplier they confirmed that they had supplied the closing reading about two weeks after the switch. However Tonik maintained that they did not have the closing reading and refused to produce the closing bill or give me my credit balance back. After 8 weeks of getting nowhere despite many contacts to Tonik, I referred my complaint to the Ombudsman and as soon as the Ombudsman resolution said the bill should be priduced, hey presto, all of a sudden Tonik could produce the final bill instantly! However, in the explanation they gave they admitted that they did have the final reading around two weeks after the switch (contradicting their previous lie) but they still did not pay the £150 they owed me! Only after I again escalated matters with the Ombudsman did my money finally get paid! Basically they did nothing unless they were forced to by the Ombudsman and my advice to anyone is to avoid this company!
