Terrible appalling company!

I made payment to Talkmobile through their automated system. They sent me a text thanking me for payment but did not register it on my account. This resulted in my plan being stopped and me being charged for individual calls, texts and data and receiving a large bill which I was forced to pay. I was asked to send bank statement via email which I have now done 5 times. Each time Talkmobile have said that it is invalid although it has all the requirements that they originally asked. Today after speaking with customer service I have now been asked to email a hard copy which I have already done previously. I am getting no where with this truely frustrating company. I am now left with no choice to take this matter up with the Financial Ombusman. Anyone considering dealing with company should do so at their peril. Please talk mobile rectify your mistakes!! Furthermore I have been passed from pillar to post, given incorrect information and blatantly lied to by customer service advisors who although very polite are not capable of resolving their mistake which is costing me dearly financially and not to mention my valuable time trying to sort out their mess. STAY CLEAR of this phone company!!!!!!
