Worst company that I have dealt with ever

My husband took 4 contracts at telkom 2 years ago for a laptop, cellphone and 2 tablets, 2 of those contracts expired in May this year,he followed instructions that he must login and cancel it on his profile but there is nothing that's shows that he even have an account with telkom, what makes the situation worse we are paying for the devices that we lost a year ago as their insurance company that they work with is also useless, now we have been paying since May last year for something we don't have and they are so quick to take money but takes forver to solve the problem. As iam writing this complaint, I lost my clients as the number that I was using for my business is one of the contracts, and I went to telkom to request Sim swaps and and I was told I can not do it as it's in my husband's account. They told me to ask my husband to write stating that I can be added as third party and he did that, but when I went to telkom benoni offices again, I was told that I can not do anything again because they can't find the letter on the system but it shows that he added me. I have been so frustrated since last, I had to change everything my logos, company profile and my business website for this nonsense and what makes it worse, we can't do anything hence the account holder works overseas and he has no way of being here and sort this matter. What we thought was a solution for my family became a nightmare for us, who ever is reading this don't do business with a telkom if you want a peace of mind and company that always look at their clients interest.
